* Unit was in a refueling outage at the time of the event and core was off loaded to the SFP

* First fire in the reactor building was a small generator lube oil fire. IAEA reports that fire was put out at 2200 EDT, March 14. ‘N Radiation levels 150-1000 mrem/hour at 1000 EDT on March 16, 2011, at site gate. (Site gate is same for each unit.)

* Second fire began at 1645 EDT, March 15, 2011 in reactor building. Fuel reported to be uncovered.

* Radiation level outside Unit 4 reported to be 30R/hour following second fire.

” High radiation dose rates measured between Units 3 and 4, source is suspected to be the Unit 4 spent fuel pool.

* The spent fuel pool’s ability to retain water is in doubt, no steam – likely dry.

* For Fukushima Daiichi site, Japanese national government issued a protective action recommendation that instructed evacuation for local residents within a 20km radius of the site boundary and sheltering in place out to 30km for residents who stayed behind

* A RASCAL run at 06:54AM (EDT) on March 16, 2011 for hypothetical combined core based on the following assumptions: Units 2 & 3 each, 33% core melt & no containment; Unit 4, full core offload 100% melt in the Spent Fuel Pool (SFP) with no roof; wind direction from West Northwest blowing out to the ocean. Results: PAG exceded at 50 miles (80.5 km) with TEDE of 24.0 rem, and CDE thyroid of 130 rem.

* Based upon the degrading situation at the Daiichi plant, the US NRC recommends that Americans within 50 miles of the Daiichi plant to evacuate the area.

” The US State Department has approved voluntary authorized departure of family members at the U.S. Embassy in Tokyo, the U.S. Consulate in Nagoya and the Foreign Service Institute in Yokohama.

o 11 C-Cstaff are in Tokyo with the Ambassador and getting information from Japanese officials.

* NRC continues to develop projections of the accident’s progression, dose estimates and Q&As, including those addressing the safety of reactors in operation in the US.

* Government of Japan has accepted US offer to conduct aerial/ground monitoring and also requested potassium iodide tablets. DOE Aerial Measurement Teams have completed fly over the Daiichi site. Awaiting results.

* The NRC has been asked to provide recommendations for solutions to the spent fuel pool issues during conference call with NISA and TEPCO.
